CONE-SHAPED REMOVAIBLE-BRIDGE SPLIT ATTACHMENT.

Specification of Letters Patent.

Patented Mar. o, 1917.

Application filed March 18-1916. Serial No. 85.1.0)

To all whom it may concern:

.lle it known that I, JUIIX Ynnnux, a subject of the Turkish Empire. and-a resident of New York. in the county of'New York and State of-New York. have invented a new and useful (one-Shaped lit-movable- Bridge Split \ttaehment, of which the following is a specification.

This invention relates to certain improve ments in the shape of bridges for teelh. and has more particularly for its object to provide means for attaching removable bridges to abutments in the mouth in such a manner that the bridges will be held very rigidly by fractional engagement with the abutments.

My invention is fully set forth in thefollowing specification, reference being had to the accompanying-drawings in which-Figure 1, represents the side elevation of the fixed member'of the attaelnnent whiehrests in thefabutting lire tooth in the inlay and in the bridge too. to receive the interlocking part of the attachment.

Fig. 2, is the top plan view of Fig. 1.

Fi 3, represents the side elevation of the lnterlm k-ing part, which tits in lixed Fig. 4, is the top plan view of Fig. 6.,

Fig. 5 shows the prepared tooth and the inlay with opening for the interlocking member. Fig. 6 shows the interlocking member used in the body of a pin tooth.

Fig. 7. represents a. section of the lower part of the mouth with a. bridge in its positi'on therein. The portion 0 he mouth In, Fig. "(two ends of C are dotted, leav-- mg room for t'wolteeth. the objeot being not to hide the.,position of the attachments.

-- The advzmtage of this? new 'coneshaped removable bridge split attachment isthat it can be easily regulated by increasing and decreasing the fractional engagement o' fitthe split projection with the wall of its receiver by spreading to a greater or lesser extent the branches of the s iit projection. Fur thermore it can be taten oft by one direction only.

What I claim is,

A cone shaped split attachment for at taehing a removable bridge to an. abutment.

in the mouth, comprising an abntmentmem her having an opening in the inlay to .re' eeii'e the tubular sphtnnd oi the interlocking connection extending from the bridge.
